| Term | Definition |
|---|---|
| Acne (acne vulgaris) | Skin disorder characterized by chronic inflammation of he sebaceous glands from retained secretions and Propionibacterium acnes (p. acnes) bacteria |
| Arrector pili muscles | Small, involuntary muscles in the base of the hair follicle that cause goose bumps and papillae |
| Barrier function | Complex of lipids between the cells that keep the skin moist by preventing water evaporation and guard against irritants penetrating the skin surface |
| Broad spectrum sunscreen | Sunscreen product that has been shown to protect against both UV-A and UV-B radiation of the sun |
| Callus | Thickening of the skin caused by continued, repeated pressure on any part of the skin, especially the hands and feet |
| Closed comedo (comedones) (whitehead) | Follicle impacted with dead cells and solidified sebum, appearing as a small white bump just under the skin surface |
| Collagen | Fibrous protein that gives the skin form and strength |
| Dermal papillae | Small, cone-shaped elevations at the base of the hair follicles that fit into the hair bulb |
| Dermatologist | Physician who specializes in diseases and disorders of he skin, hair, and nails |
| Dermatology | Medical branch of science that deals with the study of skin and its nature, structure, functions, diseases, and treatment |
| Dermis (derma, corium, cutis, true skin) | Underlying or inner layer of skin |
| Elastin | Protein base similar to collagen that forms elastic tissue |
| Epidermal-dermal junction | Top of the papillary layer where it joins the epidermis |
| Epidermis | Outermost and thinnest layer of the skin that is made up of five layers: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum germinativum |
| Esthetician | Specialist in cleaning, beautification, and preservation of health of skin on the entire body |
| Eumelanin | Type of melanin that is dark brown to black in color |
| Keratin | Fibrous protein of cells that is also the principal component of hair and nails |
| Melanocytes | Cells that produce the dark skin pigment called melanin |
| Motor nerve fibers | Fibers of the motor nerves that are distributed to the arrector pili muscles attached to the hair follicles which carry impulses from the brain to the muscles |
| Open comedo (blackhead) | Hair follicle filled with keratin and sebum |
| Papillary layer | Outer layer of the dermis (directly beneath the epidermis) |
| Papule (pimple) | Small elevation on the skin that contains no fluid but may develop pus |
| Pheomelanin | Type of melanin that is red to yellow in color |
| Propionibacterium acnes (p. acnes) | Technical term for acne bacteria |
| Pustule | Raised, inflamed papule with a white or yellow center containing pus in the top lesion or "head" |
| Reticular layer | Deeper layer of the dermis that supplies the skin with oxygen and nutrients and contains fat cells, blood vessels, sudoriferous glands, hair follicles, lymph vessels, arrector pili muscles, sebaceous glands, and nerve endings |
| Sebaceous glands (oil glands) | Glands connected to hair follicles that secret sebum |
| Sebum | A fatty or oily secretion that lubricates the skin and preserves the softness of the hair |
| Secretory coil | Coiled base of the sudoriferous (sweat) gland |
| Secretory nerve fibers | Fibers of the secretory nerve that are distributed to the sudoriferous and sebaceous glands that are. Apart of the ANS (autonomic nervous system), and help to regulate perspiration and sebum flow |
| Stratum corneum(horny layer) | Outer layer of the epidermis |
| Stratum germinativum (basal cell layer) | Deepest, live layer of the epidermis that produces new epidermal skin cells and is responsible for growth |
| Stratum granulosum (granular layer) | Layer of the epidermis composed of cells that look like granules and are filled with keratin that replace cells shed from the stratum corneum |
| Stratum lucidum | Clear, transparent layer of the epidermis under the stratum corneum |
| Stratum spinosum | Spiny layer just above the stratum germinativum layer |
| Subcutaneous tissue (adipose/subcutis tissue) | Fatty tissue found below the dermis that gives smoothness and contour to the body, contains fat for use as energy, and acts as a protective cushion for the outer skin |
| Sudoriferous glands(sweat glands) | Excrete perspiration and detoxify the body by excreting excess salt and unwanted chemicals |
| Tactile corpuscles | Small epidermal structures with nerve endings that are sensitive to touch and pressure |
| Vitamin A | Supports the overall health of the skin, aids in health, function, and repair of the skin cells, and has been shown to improve the skin’s elasticity and thickness |
| Vitamin C | Important substance needed for proper repair of the skin and tissues that promotes the production of collagen in the skin’s dermal tissues and aids in the promotion of the skin’s healing process |
| Vitamin D | Enables the body to properly absorb and use calcium and is necessary for proper bone development and maintenance as well as the rapid healing of skin |
| Vitamin E | Helps protect the skin from harmful UV sun exposure |
